@graphit0 Yes I've explored them. But only Hack MD has a free web version with persistent notes storage. CodiMD & HedgeDoc work only on-premise, in local environment == not global.
That's why I chose HMD. To share links globally

BTW: talking about your feature request: I'm currently trying to run CodiMD or HedgeDoc locally with Docker Compose to check my plugin compatibility. But they don't want to connect to the DB :frowning:
Maybe someone could help me with running those apps in Docker?
